Abstract Myogenic neoplasms of the stomach are the most common submucosal mass. Their natural history is indeterminate, and surgical resection is advised regardless of size. These lesions have typically required open resection, but a variety of laparoscopic techniques have been described. We report results of endoscopically guided, laparoscopic intragastric resection. Fourteen lesions have been excised in 13 patients in the last 3.5 years. There were eight women and five men with a mean age of 57 years (range 34-72). All patients were asymptomatic, and no lesions had mucosal ulceration. Eight lesions were located at the gastroesophageal junction, two each at the incisura and posterior body, and one each in the fundus and anterior wall of the corpus. All lesions were predominantly intraluminal, and three were transmural. The diagnosis of a myogenic lesion was confirmed by endoscopic ultrasound in eight patients. The laparoscopic/endoscopic technique included two or three, 2 or 5 mm intragastric trocars; endoscopic suture passage and specimen removal; and laparoscopic intragastric suture repair of the gastric defect. The mean operative time was 186 minutes. The mean size of the resected specimens was 3.8 cm (range 1.5-7.0). There was no mitotic activity on histopathology, and all were considered pathologically benign. The median length of stay was 3.8 days (range 3-8). There was no mortality or operative morbidity. At a mean follow-up of 16.2 months (range 1-32) there has been no local recurrences. A combined laparoscopic/endoscopic intragastric resection is most appropriate for intraluminal, benign-appearing submucosal lesions of the proximal stomach.
